The count down sale of my kindle books have started – the sooner you purchase, the more you save!

Starting as this post goes live, the sale will run until Sunday the 10th. Prices start at just 0.99 US dollars, and bumps up a dollar every 37th hour until the book is back it it’s normal price. So if you’ve been curious about my books, or just like old patents in general, now is the time to pick them up for cheap.
